COMBINED WATER, AND AIR PUMP FOR AUTOMOBILES.

Application led June 27,

To all whom t may concern.'

Be it known that we, JOHN WV. B. LADD and RALPH E. R-IoH, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Combined vWater and Air Pumps for Automobiles, of which the following is ,a full,.clear, and exact description.

Our invention relates to improvements in automobiles, and particularly to the means for operating pumps for circulating the water in the radiator and for' pumping airl into the tires of the same.

The principal object of our invention is to circulate by means of a water pump the water used for cool-ing the engine of an automobile not only through the engine but also through the water jacket of an air pump, thereby keeping the air pump cool when it is in operation. Another object of our invention is to utilize the same power that is now used to drive the car to actuate' both the pump for circulating the water through the radiator and the pump for pumplng air into the tires. Yet another object is to operate both of these pumps by one shaft that derives its motion from the engine. Yet. another objectl is to provide a very economical construction for this purpose, the cost of manufacture of which is, comparatively speaking, very small, and which can be installed easily and quickly in a position within convenient reach, at a minimum expenditure for labor. These and other objects. we accomplish, substan' tially as hereinafter fully described, and as yillustrated in the drawings, in which- Figure 1 is a side view of an engine showin our improvements applied thereto.

`ig. 2 is a front end view thereof.

Fig. 3 is an enlarged side view of the pump mechanism segregated from the driving:i mechanism.

eferring to the drawings, A represents the gas engine and 6 is the fan-shaft which` is driven through the medium of a belt by the crank-shaft. A laterally disposed trianlar shaped bracket 8 is secured by means of bolts to lthe front of the engine casing 9, and projects laterally beyond the right hand side thereof, and has a bearingt 10 in lts outer end for a longitudinal sha 12 (hereinafter referred to as the pump-shaft). The crank-shaft has' a sprocket-wheel 13, mounted thereon that is engaged by a chain Specification of Letters Patent.

journaled inthe sides of the shell or casing 15 of a rotary pump, which latter is proi vided with an integral supporting plate 17 that is bolted or otherwise secured over the intake opening in the side of a water chamber 16 inclosing the tops of the cylinders.

A short distance in front of the rotary pump casing 15, shaft 12 has a suitable gear 18 securely mounted thereon, and this gear 18 is adapted to engage a pinion 19, which latter is splined to a horizontal crank-shaft 20 so as to revolve therewith and be capable of reciprocable motion thereon.

The end of shaft 20 opposite that on which pinion 19 is mounted is provided with a crank 21, and a pitman 22 is pivotally' secured to the wrist-pin of this crank, substantially as shown. The opposite end of pitman 22 is pivoted in any suitable manner'to a piston-head 23, which engages the cylinder 24- of an air-pump, and the head of this cylinder, opposite the open end thereof through which the pitman moves, has a valve-controlled intake stub 25 and a valvecontrolled outlet stub 26. .A suitable eXible tube 27 is attached to and leads from ypoint adjacent to the inclined pipe 29 leading upward from the lower chamber of the radiator 60 of the engine, to which it is connected by a suitable couplingv 30. An outlet pipe 31 leads from this water-jacket, preferably, at a point diametrically opposite pipe 29, and this outlet-pipe `31 extends to and discharges into the center of casing 15 of the rotary pump.

We4 prefer to cast pipe 31 in one piece with pump-casing 15 and water-jacket 28 of the air-"pump, and also to cast the waterjacket and cylinder in one piece therewith in order to support the whole structure of the air-pump and rotary pump from the supporting-plate that secures the ump-casing to the side of chamber 16. e do not, however, desire to be confined to this construction, as it might, under certain circumstances, be advisable to make the pump and its several parts separately, and to connect the same to ether in accordance with well known mec ianical methods. Intakepipe 28a of the water-jacket could also be cast in one piece with the water-jacket, and at a suitable point below the lower end of the cylinder it could be provided with bearings for shaft 20, substantially as shown.

Pinion 19 is loose on shaft 20, and on the side opposite the bearings of said shaft, it has a,boss, the end edges of which are serrated to form a counterpart 32 of a longitudinally reciprocable clutch 33, whose oposing end is correspondingly serrated.

his clutch is provided with a circumferential groove which is engaged by the inturned ends of the bifurcations 34 of the lower branch of a vertically disposed lever This lever is fulcrumed at a suitable point between its ends to a lug 36 projecting` laterally from the lower portion of the water-jacket and a coil contraction spring 37 connects its upper branch to the adjacent side of the water-jacket.

It will be apparent that the principal feature of our invention is the utilization of shaft 12 to actuate the air-pump as well as the rotary water pump, and also to cool the i air pump, which heats very, rapidly, by

means of the water circulated through the radiator and water chamber of the engine. In the accomplishment of these objects, we do not wish to be confined to the exact mechanical construction, as hereinbefore described, and as illustrated in the drawings, as it is obvious modifications of the parts of our invention and changes of location of the same could be adopted without departin from the spirit of our invention.
